How to chain GateKeeper in case of multiple enclaves of firewalls?
In case there are multiple layers of firewalls between client and server, multiple GateKeepers need to be run for each firewall. The most common case is when a client is blocked by an outbound firewall and the server is blocked by an inbound firewall. The easiest way to configure this case is to run a GateKeeper outside the client-side firewall and another GateKeeper outside the server-side firewall; configure the client to always go through the first GateKeeper for IIOP request by specifying vbroker.orb.gatekeeper.ior; load firewall package on first GateKeeper and set vbroker.orb.alwaysProxy so that it will always talk to the second GateKeeper; then configure a firewall path on server so that the server can be accessed via the server-side GateKeeper. In case of multiple firewalls on server side, you can configure the server with the closest GateKeeper as its firewall path, and configure another firewall path with the second closet GateKeeper for the above GateKeeper. Or, you can confi
